Assignee:

Cardiac Pacemakers, Inc. - St. Paul MN

International Classification:

A61N 1/00

US Classification:

607 2

Abstract:

An embodiment uses an accelerometer to sense heart sounds, and determines heart rate info nation using the sensed heart sounds. An embodiment uses an accelerometer to sense respiratory activity. An embodiment delivers a programmed neural stimulation therapy with a programmed duty cycle, where the programmed duty cycle includes a stimulation ON portion followed by a stimulation OFF portion. An electrode electrically connected to the implanted neural stimulation device is used to remotely detect cardiac activity. The remotely detected cardiac activity is used to detect heart rate information during the stimulation ON portion and to detect heart rate information during the stimulation OFF portion. The detected heart rate information and/or the detected respiration information are used to control a neural stimulation therapy performed by the neural stimulator device and/or are used to provide diagnostic information for the patient's condition.

US Classification:

607 46

Abstract:

Various system embodiments comprise an implantable lead, an implantable housing, a neural stimulation circuit in the housing, and a controller in the housing and connected to the neural stimulation circuit. The lead has a proximal end and a distal end. The distal end is adapted to deliver neural stimulation pulses to the ventral nerve root and the dorsal nerve root. The proximal end of the lead is adapted to connect to the housing. The neural stimulation circuit is adapted to generate neural stimulation pulses to stimulate the ventral nerve root or the dorsal nerve root using the implantable lead. The controller is adapted to control the neural stimulation circuit to deliver a neural stimulation treatment.

US Classification:

607 9

Abstract:

According to various method embodiments, a person is indicated for a therapy to treat a cardiovascular disease, and the therapy is delivered to the person to treat the cardiovascular disease. Delivering the therapy includes delivering a vagal stimulation therapy (VST) to a vagus nerve of the person at a therapeutically-effective intensity for the cardiovascular disease that is below an upper boundary at which upper boundary the VST would lower an intrinsic heart rate during the VST.

International Classification:

A61N 1/00

US Classification:

607 17

Abstract:

Cardioprotective pre-excitation pacing may be applied to stress or de-stress a particular myocardial region delivering of pacing pulses in a manner that causes a dyssynchronous contraction. Such dyssynchronous contractions are responsible for the desired cardioprotective effects of pre-excitation pacing but may also be hazardous. Described herein is a method and system that uses measures of a patient's physiological response to ventricular dyssynchrony to control the duty cycles of intermittent pre-excitation pacing.

US Classification:

607 59

Abstract:

A neurostimulation system senses a signal indicative of a patient's physical state such as posture and/or activity level. In various embodiments, a stored value for each of stimulation parameters controlling delivery of neurostimulation is selected according to the patient's physical state. In various embodiments, values of the stimulation parameters are approximately optimized for each of a number of different physical states, and are stored for later selection.

International Classification:

A61N 1/00

US Classification:

607 28

Abstract:

A neurostimulation system includes a neural stimulation lead having a proximal portion and a distal portion and including a plurality of electrodes along the distal portion. The plurality of electrodes are configured for positioning proximate a portion of the autonomic nervous system. A neural stimulation circuit, coupled to the plurality of electrodes, delivers neural stimulation pulses to the plurality of electrodes. A processor and controller is configured to control the neural stimulation circuit to deliver first neural stimulation pulses to each of a plurality of electrode configurations. Each electrode configuration includes one or more of the plurality of electrodes. The processor and controller is further configured to receive information related to motor fiber activity that is induced in response to delivery of the first neural stimulation pulses to each of the plurality of electrode configurations and to identify the electrode configurations that induce the motor fiber activity.

Abstract:

A first fluid status indicator of a pulmonary fluid status associated with pulmonary edema and a second fluid status indicator of a non-pulmonary fluid status can be used to provide an alert or to control a therapy for pulmonary edema. Additionally, intermittent cardiac blood volume redistribution therapy can be used to provide cardiac conditioning in heart failure patients.
